Mattress ventilator



Dec. 13, 1938. E, CAVICCHI MATTRESS VENTILATOR Filed March 8, 1957Patented Dec. 13, 1938 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to ventilators and more particularly to aventilator particularly designed for use on mattresses, pillows,upholstery and the like.

The object of the invention is to provide a mattress ventilator ofsimple and inexpensive construction capable of being quickly andsecurely attached to any portion of a mattress whereby to permit thefree circulation of air through the body of the mattress andconsequently increase the effective life thereof and render the mattressthoroughly sanitary under all conditions of service.

A further object of the invention is to provide a mattressventilatorwhich may be used either with or without a retaining ring for clampingthe ventilator in position on a mattress ticking, the

parts being so constructed as to insure a firm positive grip on thecloth without danger of tearing, ripping or otherwise damaging thefabric around said ventilator.

A further object is to provide a ventilator including a flat disk-likebody portion having ventilating slots punched or otherwise formedtherein, with the metal between the walls of the slots bent outwardly toform radial clamping tongues for direct engagement with the cloth or forcooperation with a suitable retaining ring.

A further object is to provide a mattress ventilator, the body of whichis formed with stepped ribs disposed between the ventilating slots andwhich ribs not only serve to reinforce and strengthen said body but alsoimpart a distinctive ornamental appearance to the ventilator.

A still further object of the invention is generally to improve thisclass of devices so as to increase their utility, durability andefiiciency.

In the accompanying drawing forming a part of this specification and inwhich similar numerals of reference indicate corresponding parts in allthe figures of the drawing:

Figure l is a perspective view of a portion of a mattress equipped witha ventilator embodying the present invention,

Figure 2 is an enlarged front elevation,

Figure 3 is a rear or inside view,

Figure 4 is a transverse sectional view taken on the line 4--4 of Figure2,

Figure 5 is an enlarged transverse sectional view taken on the line 5-5of Figure 2 showing the construction of the stepped reinforcing ribs,

Figure 6 is a transverse sectional View showing the retaining ringomitted and the clamping 55 tongues in direct contact with the cloth,

Figure '7 is a plan view illustrating a modified form of the invention,and

Figure 8 is a similar view illustrating another form of the invention.

The improved ventilator forming the subjectmatter of the presentinvention may be used on mattresses, pillows and upholstery of allkinds, and byway of illustration is shown applied to a conventional typeof mattress in which 5 designates the top of the mattress and B one ofthe side or end walls thereof.

The device comprises a disk-like plate or body portion 1 preferablystamped or otherwise formed from sheet vmetal and which may be circularin outline, as shown, said body portion being of su fii- Cut, punched orotherwise formed in thebody portion ,7 are a series of convergingincisions ,9 arranged in pairs with one of the incisions of each pairintersecting the other near the center of the body portion, the metalbetween each pair of incisions being-bent to extend from the inner faceof the body and form tapered clamping 'spurs or tongues Ill and providesubstantially V- shaped ventilating openings H through the body or plateI. The body portion is also preferably formed with a central ventilatingopening I2 while the marginal edge of said body is preferably scallopedor otherwise ornamented, at 13, to give the ventilator a neat attractiveappearance. Associated with the disk-like body portion 1 is a flatretaining or clamping ring I4 which coacts with the inner surface of thebody 5 to clamp the fabric 8' therebetween, this clamping action beingefiected by pressing or bending the tongues I0 into position to extendradially across the retaining ring, as best shown in Figure 4 of thedrawing. When the tongues I0 are clamped in engagement with theretaining ring l4, the inner faces of said tongues will be disposedparallel to the plane of the ring so that liability of the terminals ofthe tongues cutting or tearing the mattress ticking is positivelyprevented. The bending of the tongues form inner shoulders M which bearagainst the inner marginal edge of the clamping ring and the adjacentfabric and materially assist in holding the ventilators in position onthe mattress.

' Between the ventilating openings H, the metal constituting the body Iof the ventilator is embossed or pressed outwardly to form a series ofradiating ribs l5 the side portions of which are stepped or offset withrespect to their central portions, as indicated at it and which ribs notonly serve to reinforce and strengthen the body portion I but alsoenhance the ornamental appearance of the ventilator as a whole.

Any desired number of ventilators may be used and positioned at anydesired place or places on the mattress in order to permit the freecirculation of air therethrough.

In applying the. ventilator to a mattress, the opening 8 is first formedin the cloth or ticking after which the body portion 7 is positionedagainst the outside of the mattress with the tongues passing through theopening. and the clamping ring bearing against the inner face clothopposite the marginal portion of the body; after which the tongues H]are bent into position to extend across the retaining ring I4 with theshoulders I4 in contact with the fabric and ring, respectively, therebysecurely clamping the. ventilator in position on the ticking, as will bereadily understood.

If desired, however, the retaining or clamping ring 14 may be dispensedwith, and in Figure 6 of the drawing I have shown a ventilator in whichthe cloth is clamped directly between the body portion ll of theventilator and the tongues IS, the construction and operation of thedevice being otherwise similar to that shown in Figures 1 to 4 inclusiveof the drawing. Instead of making the disk-like body portion of theventilator circular inoutline, said body portion may be substantiallyrectangular in shape, as indicated at [9 in Figure '7 of the drawing, orif desired, it may be of diamond formation, as indicated at 2B in Figure8. In fact, any desired shape may be imparted to the body of theventilator and said ventilator may be made in any distinctive design solong as the body portion of the ventilator is provided with theventilating openings and clamping tongues previously referred to.

Having thus described the invention, what is claimed as new is:

1. A mattress ventilator comprising a body formed with slits spaced fromeach other, the

material enclosed by the slits being bent to form clamping tongues andprovide spaced apart ventilating openings through the body.

2. A mattress ventilator comprising a disk-like metallic body portionhaving slits formed therein, the metal enclosed by the slits being bentto provide ventilating openings through the body and form clampingtongues extending from the inner face of the body at outer ends of theopenings, said tongues when in a clamped position having portionsextending substantially parallel to the body across the outer marginalportion thereof.

3. A mattress ventilator comprisinga body portion having spacedsubstantially V-shaped incisions formed therein with arms of eachincision converging inwardly and intersecting at their innerends, andthe metal between the arms of the incisions being bent to provideradially extending ventilating openings through the body and formclamping tongues extending from the inner face of the body at outer endsof the openings, the attached ends 'of said tongues being provided withabutment shoulders adapted to engage the cloth of the mattress and thefree ends ofsaid tongues being adapted to clamp the cloth against theouter peripheral portion of the body, the material between adjacentventilating openings being embossed to form outwardly projectingradiating ribs having portions disposed in stepped relation to eachother.

4. A mattress ventilator comprising a body portion of a size adapting itto fit over an opening in' a mattress ticking and bear against the outerface of the ticking about the opening, a clamping ring for bearingagainst the inner face of the ticking opposite the ma'rginal'edgeportion of the body, said body being formed with spaced slotsconstituting radially extending ventilating openings, and tonguesextending from the inner face of the body at outer ends of said openingsand having their free end portions bent to extend across said clampingring and cause the ticking to be clamped between the ring and marginalportions of the body.
